Abstract

A multigap color LCD device which prevents display non-uniformity arising from non-uniformity in cell thickness. The external measurements of a blue color filter within a LCD device are fabricated not to overlap the source buses and the gate buses, which surround an opposing picture element electrode, and the external measurements of a green color filter in the LCD device are fabricated to overlap a pair of source buses and a pair of gate buses, which surround the opposing picture element electrode. The distance between the green color filter and both the source buses and the gate buses, is set so that it approximately equals the distance between the blue color filter and the picture element electrode. In addition to liquid crystal, spacers are inserted between the two substrates to maintain uniformity in cell thickness. Red color filters may be the same width as the blue color filters, or wider, extending to the proximity of the blue color filters.
